Apple Inc.'s new 7-inch iPad Mini is eating up sales from its bigger brother, the iPad 4.
A poll of 50 Apple stores conducted by Citi this week found limited stock of the iPad Mini but wide availability of the iPad 4. Among the stores called, 80 percent indicated that some version of the Mini was on the shelves. But 96 percent said that overall availability was limited based on the amount, storage options and colors that consumers were seeking.
